Imagine that you wanted to understand the effects of drought on plant growth. You decided to
exclude rain from plants in 5 sites and let natural levels of rainfall occur in 5 different sites. In
this example, plant growth is the correct answers the dependant variable
Imagine that you wanted to understand the effects of drought on plant growth. You decided to
exclude rain from plants in 5 sites and let natural levels of rainfall occur in 5 different sites. In

response variable
Your colleague is planning an experiment to see whether pesticides harm fish in the Sierra
Nevada Mountains. She is planning to add pesticides to three lakes and then monitor the fish for
one year after adding the pesticide. What is the single most important way that she could
improve the experimental design of this study?
- add three more pesticide treated lakes to the study
- Add three control lakes to the study
- Randomize the way she measures the fish health correct answers add three control lakes to the
study
Which of the following represents an ecosystem service?
- Trees provide O2 through photosynthesis
- Shrubs provide erosion control by anchoring soil
- Bees provide food resources through pollination correct answers All of the above
